| 19:59 | <noob2> hi!
| |
| 20:00 | i am wondering if i want to use oss sound? does it mean i have to change it in the ltsp/i386?
| |
| 20:05 | anyone back from their xmas parties?
| |
| 20:06 | pmatulis has quit IRC | |
| 20:10 | zamba has joined #ltsp | |
| 20:11 | <johnny> why would you want oss sound?
| |
| 20:11 | oss is not even in the kernel anymore in newer versions.. i wouldn't try

| 20:25 | <sbalneav> The only reason I can think of to use oss sound is if you've got some really old hardware that was supported by oss, but isn't supported by the newer sound architechrue
| |
| 20:25 | And for the amount of trouble you'll go through to get oss to work, you'd be better off to turf the old hardware.
| |
| 20:26 | either that, or just SOUND = N
| |
| 20:29 | <noob2> oh
| |
| 20:29 | becoz when i do play sound on my thin client using rdesktop to a windows
| |
| 20:29 | <johnny> rdesktop doesn't require oss
| |
| 20:29 | <noob2> a get a bunch of "fooo!"
| |
| 20:29 | and the sound stutters
| |
| 20:30 | online documentations give me the impression that I should change it to OSS
| |
| 20:30 | <sbalneav> I don't know much about rdesktop.
| |
| 20:30 | <noob2> which i did on my server i installed OSS 4.x
| |
| 20:31 | the sound on the server works but i got no sound on my thin clients
| |
| 20:31 | <sbalneav> oss on the server wouldn't fix sound on the thin clients
| |
| 20:31 | <noob2> so i am wondering if i have to tweak the i386
| |
| 20:31 | instead..
| |
| 20:31 | <sbalneav> probably
| |
| 20:31 | you'd be on your own for that, though.
| |
| 20:32 | <noob2> anyways
| |
| 20:32 | lets do an anlogy though
| |
| 20:32 | so if i wanted say, a new program on my thin clients, how do i do that?
| |
| 20:32 | do i login to the administrator account on a thin client?
| |
| 20:33 | or do i somewhat change the chroot?
| |
| 20:33 | as i am still new to ltsp istill need a direction
| |
| 20:34 | <sbalneav> !docs
| |
| 20:34 | <ltspbot`> sbalneav: "docs" :: For the most current documentation, see https://sourceforge.net/apps/mediawiki/ltsp/index.php?title=Ltsp_LtspDocumentationUpstream
| |
| 20:35 | <sbalneav> Are you running localapps, or all programs on the server?
| |
| 20:35 | if you're running them from the server, just install them on the server as you normally would.
| |
| 20:35 | <johnny> i would suggest against this noob2 ..
| |
| 20:36 | <noob2> so u mean i just do a normal install in the server?
| |
| 20:36 | <johnny> if something doesn't work with alsa..
| |
| 20:36 | <noob2> why?
| |
| 20:36 | <johnny> then getthem to fix the program
| |
| 20:36 | or talk to the authors and find out if you're reading obsolete docs
| |
| 20:36 | nobody here who uses rdesktop has ever mentioned oss
| |
| 20:36 | i'd suggest trying back in a few hours
| |
| 20:36 | as in.. the next day for usa..
| |
| 20:37 | talk to other folks who use it before mucking with something you don't understand
| |
| 20:37 | <noob2> oh
| |
| 20:37 | i already changed the OSS sound in the server...
| |
| 20:37 | <johnny> change it back?
| |
| 20:37 | <noob2> i supposedly have already changed it ...
| |
| 20:37 | <johnny> alsa already comes with an oss emulation module
| |
| 20:38 | so you shouldn't have had to do anything at all to use apps that did'nt work with alsa
| |
| 20:38 | <noob2> let me see if i can find the webpage that told me to change it../
| |
| 20:38 | it does??
| |
| 20:38 | <johnny> yes
| |
| 20:38 | <noob2> that is wonderful news.......
| |
| 20:38 | <johnny> i wouldn't trust any docs related to sound that are greater than 2 years old

| 20:38 | <johnny> or really much of anything related to linux..
| |
| 20:39 | things change so quickly..
| |
| 20:41 | <noob2> so there are pple here using rdesktop to windows>
| |
| 20:41 | <johnny> yes
| |
| 20:41 | using it from the chroot tho..
| |
| 20:41 | as in.. booting directy to rdesktop
| |
| 20:42 | without going into gnome
| |
| 20:42 | <noob2> https://bugs.launchpad.net/ubuntu/+source/rdesktop/+bug/379636
| |
| 20:43 | oh, last time i posted a question... did not think there were pple doing that... maybe my question was too dumb....
| |
| 20:43 | <johnny> you can't do anything of that
| |
| 20:44 | you need pulseaudio for ltsp to work
| |
| 20:44 | oh wait.. perhaps they do it another way..
| |
| 20:44 | since rdesktop is installed in the chroot?
| |
| 20:44 | that's my guess.. i've never used it
| |
| 20:44 | but you should already have /dev/dsp is alsa-oss is loaded
| |
| 20:45 | noob2, can you post on ltsp-discuss list?
| |
| 20:45 | <noob2> it givves me an error if i recall correctly
| |
| 20:45 | <johnny> other people can help
| |
| 20:45 | just say you're having an issue and point t that ticket
| |
| 20:45 | don't describe how you think you might need to fix the problem.. just describe the problem
| |
| 20:45 | <noob2> anywyas, the thing is, when i was playing sound... everytime it stutters i get a fooo!
| |
| 20:45 | <johnny> that way you won't have to wait for somebodoy to show up here
| |
| 20:45 | yes.. i know
| |
| 20:45 | <noob2> where is this list?
| |
| 20:45 | <johnny> just post that
| |
| 20:45 | to ltsp-discuss
| |
| 20:45 | <noob2> that's a webpage?
| |
| 20:45 | <johnny> it's on sourceforge.. that's all i know..
| |
| 20:46 | no.. it's a mailing list that you have to subscribe to
| |
| 20:46 | loather-work has joined #ltsp | |
| 20:46 | <noob2> oh...
| |
| 20:46 | <johnny> just search for ltsp-discuss on a search engine.. i'm not sure..
| |
| 20:46 | <noob2> lol, i never joined a mailing list...
| |
| 20:46 | <sbalneav> noob2: This isn't an LTSP issue
| |
| 20:46 | it's an rdesktop issue.
| |
| 20:46 | loathsome has joined #ltsp | |
| 20:46 | leio has joined #ltsp | |
| 20:46 | <johnny> sbalneav, sure.. buti bet our folks know how to get around this issue
| |
| 20:47 | i've never heard anybody who uses rdesktop here mention the problem
| |
| 20:47 | <noob2> hmm... maybe does not exist when rdesktop from shell...
| |
| 20:48 | <johnny> well that's how most people run it
| |
| 20:48 | i think
| |
| 20:48 | they make it so some clients boot directly into rdesktop
| |
| 20:48 | <sbalneav> I'd personally say you'd get better help by talking to the rdesktop people, but that's just me.
| |
| 20:50 | <noob2> sigh... all that OSS work for nothing...
| |
| 20:50 | at least i did not break my box, last time i followed some guide...my box died...
| |
| 20:50 | <sbalneav> Don't let me stop you
| |
| 20:51 | do whatever you'd like. All I'm doing is pointing out that this is clearly a problem with rdesktop.
| |
| 20:51 | <noob2> oh
| |
| 20:51 | <sbalneav> ultimately, to get the problem solved, you don't deal with the project that simply uses rdesktop
| |
| 20:51 | you deal with the project that WRITES rdesktop.
| |
| 20:51 | <noob2> yeah, but becoz i am still not sure how ltsp is set up
| |
| 20:52 | the structure of ltsp
| |
| 20:52 | <sbalneav> If you're unsure how to drive, you don't contact ford for driving instructions.
| |
| 20:52 | <noob2> since i know there's a main directory then a ltsp/i386
| |
| 20:53 | <sbalneav> and I have pointed you to the docs
| |
| 20:53 | !
| |
| 20:53 | !docs
| |
| 20:53 | <ltspbot`> sbalneav: "docs" :: For the most current documentation, see https://sourceforge.net/apps/mediawiki/ltsp/index.php?title=Ltsp_LtspDocumentationUpstream
| |
| 20:53 | <sbalneav> have you read them all the way through?
| |
| 20:54 | <noob2> oh.. sorry.. did not know the docs is for me... =P
| |
| 20:54 | <sbalneav> There was nobody else we were talking to in here :)
| |
| 20:55 | Someone may know a workaround on the mailing list, but it will only be a workaround.
| |
| 20:55 | If you want a FIX, you'll need to talk to the rdesktop people.
| |
| 20:57 | <noob2> okay
| |
| 20:57 | will do that later
| |
| 21:02 | <sbalneav> From the rdesktop source
| |
| 21:02 | <noob2> have to go to the doctors...i've been such a bad boy, santa decided to make me ill for xmas....sob*
| |
| 21:02 | <sbalneav> rdpsnd_alsa.c
| |
| 21:02 | if ((len = snd_pcm_writei(out_handle, out->p, ((MAX_FRAMES < len) ? MAX_FRAMES : len))) < 0)
| |
| 21:02 | {
| |
| 21:02 | printf("Fooo!\n");
| |
| 21:02 | snd_pcm_prepare(out_handle);
| |
| 21:02 | len = 0;
| |
| 21:02 | }
| |
| 21:02 | So, the snd_pcm_writei is returning probably a -1
| |
| 21:02 | Return values: -EBADFD PCM is not in the right state (SND_PCM_STATE_PREPARED or SND_PCM_STATE_RUNNING) -EPIPE an underrun occurred -ESTRPIPE a suspend event occurred (stream is suspended and waiting for an application recovery)
| |
| 21:03 | Seems like something's not prepared.
| |
| 21:03 | 1) they're not actually checking the result code to determine if the retcode's EBADFD, EPIPE or ESTRPIPE
| |
| 21:04 | 2) if they're doing a snd_pcm_prepare AFTER the writei's failed, looks like they're closing the barn door after the horse has already gotten out.
| |
| 21:04 | 3) Whoever thinks "Fooo!
| |
| 21:04 | is a good error message needs their head examined.
| |
| 21:20 | <Ahmuck-Jr> lol, Foo for an error code
